;2. A high. pressure sheet metal container comprising'a body portion having anopen top, a cover. forming an expansion dome over the topof said container, seating and supporting means provided between said body portion'and saidgcover; locking means for locking said seating and supporting means together, an expansion member having op-,

positely expanding sides between said body portion .and said cover to simultaneously expand against opposing sides of said cover and said body portion adjacent to said seating and supporting means to form a seal between them and the seatchamber with said body portion and said inwardly ing and supporting ,means independent of; the engagement between said seating and supporting 3. A high'pressure sheet metal container comprising a body portion having an open top sur: rounded by an inwardly projecting flange, a cover forming an expansion dome over theopen top of said container, an annular flange surrounding said cover and adapted to reston said flange of said body portion; locking means for locking said flanges together, ,an extension formed on said cover and projecting below said annular flange thereof into said flange of said body portion, said extension forming an annular sealing pr ojectitng flange thereof, and pressure expanding sealing means located in said sealing chamber and adapted to be forced against said inwardly projecting flange andexpanded against said cover extensionand said body portion to form a seal between said cover and said body portion independent of the engagement between them. r

4. A high pressure rounded by a metallic supporting seat, an expansion dome forming a cover adapted to telescope into the open top of, saidbody portion, a metallic seat surrounding said cover and adapted to seat itself on said seatof said body portion to form an inverted U shaped sealing "chamber-between, said cover and said bo dy portion, fastening means for fastening said metallic seats together toprovide a strong metallic joint between them, a sealing member located in said sealing cham-' ber, said sealing member being channel shaped and having outwardly flexing sides so that the sheet metal container com- I prising a body portion having an open top surpressure of the medium inserted into the container will force the bottom of the channel shaped tainer and the sides of said sealing member against opposing sides of the cover andcontainer body in said sealing chamber.

5. In a high pressure sheet metal container the sealing member againstsaid flange of said coni r combination of a container body having an open end, an inwardly projecting annular flange surrounding said open end and forming a supporting seat thereon, an inwardly projecting annular,

ridge in said container body and forming a horiwith said dome in contact with said expansion member andfastening means for fastening said expansion dome to said container body.
